Dynamic Sampling and Rendering of Algebraic Point Set Surfaces
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
Algebraic Point Set Surfaces (APSS) define a smooth surface from a set of points using local moving least-squares (MLS) fitting of algebraic spheres. In this paper we first revisit the spherical fitting problem and provide ...
Lighting and Occlusion in a Wave-Based Framework
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We present novel methods to enhance Computer Generated Holography (CGH) by introducing a complex-valued wave-based occlusion handling method. This offers a very intuitive and efficient interface to introduce optical elements ...
